GDP and Welfare

GDP is a measure of marketed production, not a complete measure of environmental well-being. If air quality deteriorates without a corresponding market transaction, the loss may not be deducted from measured GDP. People can therefore suffer poorer health and quality of life while recorded output stays unchanged. Hence option A is correct; productivity and public-health improvements generally support welfare, while price stability is not itself this environmental loss.

The relevant concept is the composition of output. GDP adds the market value of final goods and can remain constant even when the mix of goods changes. Weapons may contribute to measured GDP, but fewer consumer goods can reduce direct consumption benefits; the welfare effect also depends on security needs and social priorities. Therefore option C is the careful conclusion. Options A and B claim certainty, and D incorrectly excludes weapons from GDP.

Real output per person equals the real GDP index divided by the population index. Initially the ratio is 120/100 = 1.20; later it is 126/108, approximately 1.167. Equivalently, real GDP rises by 5% while population rises by 8%, so population grows faster than output. Therefore real output per person falls, making option B correct. It neither stays unchanged nor doubles.

Public parks provide a non-market or publicly provided amenity. Greater access can improve recreation, health, and quality of life, so welfare may rise. However, if no additional market payment or recorded production occurs, the full benefit is not added to GDP; measured GDP may change little. Thus option B is correct. Equal movement is not necessary, and the other choices contradict the likely welfare effect.

Medical treatment purchased in markets is recorded as final expenditure and can raise measured GDP. But the disease creates pain, lost health, reduced activity, and other welfare losses. The increase in medical sales may therefore reflect defensive spending needed to repair harm rather than improved well-being. Option B correctly separates production measurement from welfare. Option C is false because medical services can be final services, and A and D overstate the evidence.

Real GDP is obtained by separating price changes from changes in quantities and quality, but a price index may fail to record improved quality. If better products are treated as merely the same products at different prices, the statistical measure can miss part of the real gain. Consequently, growth in real output and welfare may be understated, so B is correct. The other options either reverse the bias or make unrelated claims.

GDP is useful because it summarizes the market value of final goods and services produced, providing information about income and material consumption possibilities. It is incomplete because welfare also depends on distribution, unpaid work, environmental quality, leisure, health, education, security, and the quality of goods. Therefore option B gives the balanced conclusion. A is too absolute, while C and D wrongly deny other relevant information.

GDP generally values production through market transactions or imputations with observable prices. When a household hires a domestic worker, a paid service creates recorded income and expenditure; when a family member performs the same task unpaid, it is usually outside measured GDP. This unequal treatment shows the limitation of market-based valuation and the omission of non-market household work. Therefore option B is correct, not depreciation, borders, or double counting.

The governing concept is that aggregate income and its distribution are different dimensions of economic welfare. If total real income increases while median income falls, the gains are likely concentrated among higher-income households, while the typical citizen becomes worse off. Therefore, option B is correct. Option A is too absolute; options C and D do not follow from the information given.

GDP records the market value of timber produced, but conventional GDP does not automatically subtract the loss of natural capital caused by forest depletion. Consequently, current measured output can appear higher even though future productive capacity and sustainable welfare decline. Option A is correct. The other options concern population, nominal-output understatement, or distribution, none of which follows from the stated omission.

Economic welfare is multidimensional. Real GDP per capita measures average real output or income, whereas life expectancy reflects an important health and quality-of-life outcome. If the first rises and the second falls, the indicators send conflicting signals, so option B is correct. Option A wrongly assumes GDP alone determines welfare; C excludes a relevant welfare dimension, and D contradicts the premise.

Per-capita real GDP is calculated by dividing real GDP by population. Since ₹1 crore equals ₹100 lakh, ₹900 crore equals ₹90,000 lakh. Therefore, ₹90,000 lakh ÷ 15 lakh people = ₹6,000 per person. Option A is correct. The other choices result from mishandling the crore-to-lakh conversion or dividing incorrectly.

GDP measures the market value of produced goods and services, but it does not directly subtract unpaid time lost in congestion, reduced leisure, stress, or fatigue. Thus, output can rise while quality of life and welfare decline. Option B is correct. A is too strong because commuting expenditure may itself support measured production; C and D make unsupported claims about congestion and exports.

GDP records qualifying government production and expenditure, but it does not by itself judge whether that spending improves social welfare. War may create security benefits while also causing deaths, destruction, displacement, and opportunity costs. Therefore, option B asks the relevant net-social-benefit question. A and C concern accounting inclusion, while D is unrelated to the welfare issue.

Consumer welfare depends on the utility or benefit received, not only on the price paid. A digital service priced at zero can provide substantial convenience, information, or entertainment, creating consumer surplus. Advertising revenue may record some market activity, but GDP may not fully capture users’ unpaid benefit. Thus option B is correct; A and D confuse zero price with zero value, while C is an unjustified universal claim.

Sustainable welfare requires maintaining the productive and ecological assets on which future generations depend. Rapid extraction can increase current GDP, but depletion of forests, minerals, soil, or water may reduce future production capacity and quality of life. Option B states this intertemporal trade-off. A and D deny resource dependence, while C is too narrow because depletion can affect real as well as nominal outcomes.

The governing concept is that real GDP per capita is only a partial indicator of welfare. Perfect equality removes the distribution problem, and higher real output may increase access to goods, but welfare also depends on environmental quality, health, leisure, security, freedom, and the quality of goods. Therefore option B is correct; A and C wrongly treat GDP as complete, while D wrongly denies the usefulness of real GDP.

The governing concept is distribution-sensitive measurement. Total GDP shows the size of economic activity but not who receives the gains. Median household income identifies the income of the middle household after arranging households by income, so it is less distorted by a small number of very rich households. Option B is therefore the best indicator. Total GDP, capital formation, and government consumption do not directly show the typical household’s income.

GDP records the market value of goods and services, including medical treatment and repair services generated after accidents. It does not subtract pain, reduced quality of life, lost leisure, or the intrinsic cost of injury in a complete way. Thus output and accident-related spending can rise together while welfare falls, making option B correct. A, C, and D contradict how GDP is measured.

Nominal GDP is valued at current prices, so its growth combines changes in physical output with changes in the price level. If most growth comes from rapid inflation, the quantity of goods and services may have risen little or even fallen in real terms. Option B is therefore correct. Stable prices with higher output are less misleading, while population and public-service changes require separate analysis.
